Specification of Letters Patent.

Patented May 9,1916.

Application filed March 4, 1916. Serial No. 82,014.

To all whom it may concern Be it known that 1, WILLIAM H. REID, acitizen of the United States, and a resident of Brooklyn, in the countyof Kings and State of New York. have invented certain new and usefulImprovements in Separable Fasteners, of which the following is reason ofa special form of a tongue member, that is formed by merely providing aspecial configuration of the edges of the blank, and which tongue isgiven the special bending operation.

A further object of the invention is to provide such a construction inwhich the socket member will be integral with the tongue, so that thedevice comprises simply two members, the spring member and the bodymember.

In the accompanying drawing showing one embodiment of my invention,Figure 1 is a plan view of the device. Fig.2 is a vertical section onthe line 2-2 of Fig. 1. Fig. 3 is a vertical section on the line 33 ofFig. 1; Fig. 4: shows a head member that cooperates with the socketmember'of Fig. 1. Fig. 5 is a plan view of the spring member. Fig. 6shows the blank as cut out. Fig. 7 is an edge view of the blank. Fig. 8shows the blank with the head portion of the tongue pressed into finalshape. Fig. 9 is a side elevation of the blank as shown in Fig. 8. Fig.10 shows a blank of Fig. 9

with the tongue bent over on to the base;

and Fig. ll is a section through the form of button as at present inuse.

Heretofore fasteners of this character have been provided in which thebase 12 has a head 13 formed integral therewith by a simple dieoperation of expanding the center of the blank to form a substantiallysemi-spherical head or cap, as shown m Fig. 11. This cap has beenprovided with openings or slots 1% and 15 on two opposite sides, adaptedto receive a spring similar to the spring 16 shown in Fig. 5. Thisspring had its end portions 17 and 18 projecting into the slots 14. ans.15, to engage the head on the head member, such as the head 19 on themember 20, as shown m Fig.

1 But it has been found very difficult in practies to produce theopenings 11 and15 in the members, by reason of their being of a verysmall size. T o-overcome the necessity of cutting or punching suchslots, I provide a button which has a base member 21, and a cap member22 in the form of a band having an enlargement at its middleportion.This band is preferably made integral with the base member, as shown,and is provided in the blank with a, circular enlargement23 connected bya strip 24 with the base 21, and having astrip 25 at the free end. Thed1sk port1on '23 is engaged by proper dies to give it a cap shape 26,preferably'semispherical and this cap has upright portions 1 21 and 28,that extendvertically downward from the cap, and are formed by'bendingupward the portions of the strips 21 and 25 ad acent the cap, asindicated in Fig. 9. By th s means it will be seen that the cap willhave its opposite sidesbetween the upright portions 27 and 28 free, andwhich are off-set from the plane of the strip portions 21 and 25. Thecap niemberis next bent portions 2+1 and 25 of the band will engage thebase between the spring ends. This form of a member usually is the sideedges bent over or beaded as at 30. to engage the outer portion of thespring 16 and-hold it I in position. The strip portion 21 is preferablybent over on top of this spring, as indicated in Figs. 2 and 10. Theextremity of the cap member or strip '25, will also be engaged by thebead 30 that will serve to retain the cap member in position on the base21. It will thus be seen the spring portions 17 and 18 will lie beneaththe portions of the cap member, that will overhang them and preventtheir being forced upward by the head 19. These spring members willproject across opposite portions of the bore 29. as indicated in Fig. l,andwhen the head enters the socket, the spring members will grip theheadand retain the two members together in locked position. It will befurther seen that the spring mem bers engage the side edges oftheupright portions 27 and 28, that limit the inward movement of the springmembers, as clearly shown in Figs. 1 and 4..

It will thus be seen that l have provided a construction in which thereis a head mem- I be'r'havingundercut portions on two opposite sides toreceive the spring, members and hold them properlyshaped to engage thehead member; and that the spring members are prevented'from being forcedup- Ward by the head, because of the overhanging of the cap members. Butsuch-construction is provided without any'openings being formed in thecap member at any stage in the manufacture, and is a result of the con-:figuration of the margins of the blank and of very simple bendingoperations.

Having thus described my invention, what I claim is 1. A resilientsocket member for a head and socket fastener, comprising a base memberhaving acentral bore to admit the head, a member extending across thebase and having two upright portions adjacent the bore margins connectedat the top by a portion whose 'the said upright portions,

dome shaped portion whose opposite sides project over said bore marginsbetween said upright portions, and a wire spring on the base havingportions extending across the margins of the said bore in the baseadapted to engage the head, which said spring portions lie beneath thesaid dome portions and engage the said upright portions.

2. A resilient socket member for a head and socket fastener, comprisinga base member having a central bore to admit the head, a memberextending across the base and having-two upright portions adjacent thebore connected at the top by a dome-shaped OPDOSltG sides project oversaid bore margins between said upright portions, and a wire spring onthe base having portions extending across the margins of the said borein the base adapted to engage the head, which said spring portions liebeneath the said dome portions and engage the said base member havlngits margins beaded to inclose a part of the spring member and to securethe said dome member at its ends to the base.

3. A resilient socket member fora head and socket fastener, comprising abase. member having a central bore to admit the head, an integralextension of the base member bent over to lie against the base andhaving two upright portions adjacent the'bore margins connected at thetop by a dome-shaped portion whose opposite si es overhang the boremargins between said upright portion,-

and a wire spring on the base having portions extending across themargins of the said bore in the base adapted to engage the ed at the topby a dome portionwhose opposite sides overhang the bore margins betweensaid v upright portions, and a wire spring on the base having portionsextending across'the margins of the said bore in the base adapted toengage the head when inserted, which said spring portionslie beneath thesaid dome portion and engage the said upright portions of the saidextension, the said base member having its margins beaded to inolose apart of the spring memberv and .to secure the said extension at its ends.to the base.

5. A resilient socket member for a head and socket fastener, comprisinga base member having a central bore to admit the head, a non-aperturedcap member extending across the base and provided with a dome shapedportion whose opposite side edges overhang the bore margins, and a wirespring on the basehavingportions extend ing across the margins of thesaid bore in the base adapted to engage the head member when inserted,which said spring portions lie beneath the said cap projections,

and which normally engage the margins of said cap member to hold thespring in said head-engaging position.
